IMPROVEMENTS ON THE MEDNET BROAD-BAND NETWORK FROM THE VIEWPOINT OF TOMOGRAPHIC STUDIES

Our work aims to provide a methodology to assess path coverage of a do main from a tomographic viewpoint, and for the design of an improved o r new seismic network. This methodology permits different simulations through a rigorous procedure based on both mathematical and seismologi cal aspects. In this sense, some concepts of mathematical information theory and Monte Carlo methods have been combined with the aim of impr oving the epicentre-station path coverage offered by the MedNet broadb and seismic network in the Mediterranean area for a surface wave tomog raphy problem. The best path coverage is obtained without the constrai nt of including locations of existing stations. Nevertheless, even in the case of a network already installed over a region, as is the case of MedNet, our technique allows new station sites to be assessed since , it predicts improvements in the path coverage.
